Struct situ::Ref

source · [−]

pub struct Ref<'a, T: ?Sized> { /* private fields */ }

Expand description

An immutable reference, like &T.

Internally, the reference is stored as a pointer to avoid provenance narrowing.

Implementations

source

impl<'a, T: ?Sized> Ref<'a, T>

source

pub unsafe fn new_unchecked(ptr: *const T) -> Self

Creates a new Ref from a shared pointer.

Safety

ptr must be non-null, properly aligned, and valid for reads.
ptr must not alias any other mutable references for 'a.
The value pointed to by ptr must be initialized.

source

pub fn as_ptr(self) -> *mut T

Returns a pointer to the referenced value.
